Use of companionSymbol in the backend witnesses stale class files #402
Description
⚡ tail /tmp/1/* /tmp/2/*

package p1;
public class A {
public static class B {
void foo() {}
static void bar() {}
}
}

void foo() {}
}
}

class Test {

In the debugger, I can see that the MethodInlineInfo includes the static method from the stale class file, as built:
val methods = if (!classSym.isJavaDefined) classMethods else {
val staticMethods = classSym.companionModule.info.decls.iterator.filter(m => !m.isConstructor && keepMember(m))
staticMethods ++ classMethods
}The isCodefinedWith check seems insufficient for nested classes after flatten.
